The evacuation was completed in 55 seconds. People in the back were stranded/unconscious/buckled-up before the plane even stopped. The eyewitness reported (see links in my post) he had to _crawl on all fours_ out of the plane through thick smoke through a completely clear aisle. People with bags were the ones sitting immediately in the first few rows, they did not cause a congestion.
I would be pissed off as anyone if luggage grabbers killed someone, but it seems they weren't the "deadly stupidity" here? I mean, the dude just wrote the whole pompous blog post with a flashy title off an unlikely rumor?
